The evolution of the NFL:
Take a look at how the NFL has evolved from its humble roots, and the efforts being made to ensure it continues to grow.

Patriots wide receiver Danny Amendola left with a head injury and did not return after taking a nasty hit in the fourth quarter. He appeared to lose consciousness.

New England's No. 1 cornerback, Aqib Talib, who shut down Jimmy Graham much of the day, injured his hip flexor, NFL Media Insider Ian Rapoport reported Sunday night. A source who spoke to Talib told Rapoport that the injury doesn't seem to be serious, but there likely will be more clarity Monday.

Center Dan Connolly also got knocked out with a head injury, and linebacker Jerod Mayo hurt his shoulder in the fourth quarter.

Graham, meanwhile, also left with an ankle injury. He was able to return after getting the ankle taped, but he looked hobbled. Graham eventually had to be helped to the locker room late in the fourth quarter. Running back Darren Sproles was shaken up briefly, but it didn't look serious. New Orleans' best defensive player, Cameron Jordan, also missed time in the game.

5. Buffalo Bills starting quarterback Thad Lewis stayed in the game during the team's overtime loss to the Bengals, but he left the stadium wearing a boot. The team says he has a foot sprain. Matt Flynn is in Buffalo for a workout Monday. (It sounds like the workout was scheduled before Lewis' injury.)
